TOOTH-POVJDER-CAN TOP.

Specification of Letters Patent.

latel'ited Feb. 2], 1911.

Application tiled May 9, 1505. Serial No. 259,63?

To all whom it may concern:

ie it known that. l, (oxnao Dniomuimain, a citizen of the United States,residing at San Francisco, in the. county of San Fran (:isco and Stateof California, have invented certain new and useful lmpriweinents inTooth-Powder-t an Tops, of which the following is a specification.

This invention relates to a tooth powder can top, of that class in whichthe can can be opened with one hand in a single operation, and willauton'iatically close upon being released by the hand.

A 11 obj ectof? this invei'ition is to provide a tooth, powder can topof this class which can be. manufaetured at minimum cost oi? time andlabor in assembling and positively fixing the several parts of the cantop together.

Can tops of the class to which this improvement pertains are providedwith a tele scopic cap for the closed neck of the can which neck and capare perforated to omit the contents of the can when the cap isdepressed, against the tension of a spring that normally holds the capin extended position to close the perforations and prevent pass sagetherethrough of air or other material in either direction.

In the accompanying drawing, Figure 1 is a perspective view showing thetooth powder can in use; Fig. 2 is an enlarged vertical section of thetop of the can showing the same closed; Fig. 3 is a similar view showingthe same open; Fig. 4 is a transverse section of the mouth of the can.

Referring to the drawing, 1 represents the body of the can which is of acylindrical form closed at the bottom, and 2 represents the top of thecan. Said top is continued into a cylindrical neck 3, closed by a top 4,concave on the outside to form a seat for a coiled spring 5. Telescopingover said neck 3 is a cap 6 the upper end of which is concaved on theinside to form a seat 7 for the upper end of said coiled spring. In theside of the neck is formed an orifice 8, and a similar orifice 9 isformed in the cap 6. The spring 5 is compressed between the seats 4 and7, and tends to press the cap upward or away from the neck, but thismovement is limited by an inwardly extending rib 10 in the side of thecap, which enters a groove 11 formed in the outside of the neck, theupper shoulder of said rib engaging the upper end of the groove to limitthe upward movement of said cap on said neck. At the same time theengagement of the rib with the groove prevents the cap l. eing turnedabout the neck, and thus retains these parts in such posit ion that thetwo orifices S, 9, bear the same angular relation to the. axis of thecan. These orifices are formed in the cap and neck respectively in suchlocations that, when the cap is depressed as far as is perinittedagainst the. pressure of the coiled spring, the orifice in the cap isbrought im inediately over or in register with the oritic-o in the neck,thus providing a tree outlet of the powder or whatever the receptaclemay contain. lint upon removing the finger from the top of the cap thespring expands, closing the orifice in the neck, and thus closing thepowder can.

It. will be observed with the construction here shown the sprii'ig isentirely removed from contact with the powder while also concealed fromview. Thus the can top presents a neat. and attractive appearance, atthe same time the powder is maintained out of contact with the springand prevented from being injured thereby if the spring has become rusty.

The form and arrangement of the rib 10 and groove 11 constitute animportant feature of the presentinvention. It will be ob served that theinwardly extending rib 10 reaches the edge of the cap 6. It. can thus beformed in a single operation with the groove 11 by placing the parts inthe position shown in Fig. 2 and then stamping the rib l0 and groove 11in a single operation. On account of the rib 10 extending entirely tothe edge of the cap 6, the groove 11 in the neck 3 can be formed by asuitable die' at the same time that the rib 10 is formed, by pressinginward both the metal. of the rib 10 and the groove 11. VVhen'this isdone the cap (3 is secured upon the neck 3, and cannot be withdrawntherefrom. This enables the device to be constructed very cheaply for itconsists of only three parts, the neck, the cap, and the spring, andonly a single operation is required to connect these parts and to formthe rib and groove which have a sliding engagement with each other.

The neck is inwardly cupped and the cap outwardly cupped, as shown, inorder to hold the spring firmly in position, thus to expedite the workof assembling, and also to jection at the top of the can.

'I claim A tooth powder can top comprising a neck having an orifice anda depressed seat in its top, a cap sliding longitudinally on said neckhaving an upwardly lmpressed seat in its top and having an orifice inits side adapted, when the cap is depressed to register with the orificein the neck, a spring between the head of the neck and the cap andseated in said seats and normally extending said cap, the

neck being formed with a groove on the outside, and the cap being formedwith an inwardly extending rib entering said groove to prevent rotarymovement of the cap on the neck, the end of the rib abutting against theend of the groove to limit the upward movement of the cap, and the ribextending entirely to the lower edge of the cap, substantially asdescribed.

In witness whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
